This course was a pivotal moment in my career, and will change the way I approach stain removal in works of art on paper. Until now, conservators have been limited to using oxidizing or reducing agents on tenacious stain complexes, which can be damaging to the cellulose. Chelation agents open up a whole new world of possibility. They remove metals, which in many instances are the source of stains in paper. But they do not damage the cellulose, making them a much more desirable option for treatment over oxidizing & reducing agents. The staff and facilities at the Art Institute are top notch, and the course was incredibly informative.
